nee-oh-DIM-ee-uhm
/ˌniːoʊˈdɪmiəm/
Neodymium is pronounced nee-oh-DIM-ee-uhm (/ˌniːoʊˈdɪmiəm/). Neodymium is a chemical element, a soft, silvery-metal rare earth metal used in magnets and high-strength alloys. It’s part of the lanthanide series, with symbol Nd and atomic number 60. The word is borrowed from Greek roots referring to its newness, and it’s commonly pronounced with three distinct syllables in scientific and industrial contexts.

How to Pronounce Neodymium
"The study focuses on neodymium magnets used in headphones and loudspeakers."
"Neodymium-doped lasers are essential in precision cutting and medical applications."
"Researchers sampled neodymium concentrations to understand mineral deposits."
You say ne-OD-ee-um with primary stress on the second syllable. IPA US: /ˌniːˈdoʊ.di.əm/ or /ˌneɪˈdoʊ.dɪ.əm/? In careful US pronunciation, it’s /ˌni oʊ ˈdiː əm/? The canonical guidance emphasizes /ˌniːˈdoʊ.diː.əm/ depending on regional drift; most scientists favor /ˌniːˈdoʊ.di.əm/ or /ˌneɪˈdoʊ.di.əm/ in casual speech. Listen to technical pronunciations on Forvo or Pronounce to confirm local variant. Mouth position: start with a long
Common errors: misplacing stress (putting main stress on the first syllable ne- instead of -ody-), slurring the middle vowels (rendering /doʊ.di/ as /də/ or /di/ as /dɪ/), and merging syllables too quickly (neod-y-dium). Correction: practice the three distinct syllables ne-O-d-ee-um? Focus on stressing the second syllable, elongate the /oʊ/ vowel, and separate the middle vowels clearly: ne-OD-ee-əm. Use slow repeats in isolation before full-word production.
In US, most say /ˌniːˈdoʊ.di.əm/ with a rhotic r? No /r/ here; rhoticity affects surrounding contexts. UK tends to /ˌniːˈdəʊ.di.əm/ or /ˌnɛˈdəʊ.di.əm/? AU often aligns with US but with slightly flatter vowels; /ˌniːˈdoʊ.di.əm/ or /ˌnaɪˈdoʊ.di.əm/? Differences mainly center on the second vowel quality and the final syllable: US /di.əm/ vs UK /dəˈʊm/? Realistic: UK often uses /ˌniːˈdəʊ.di.əm/ with a rounded /ɔʊ/ diphthong in -oʊ/ becoming /dəʊ/; AU similar but less pronounced. Check Cambridge/Oxford pronunciations for precise transcriptions.
Two main challenges: the three-syllable structure with mid-word vowel clusters /oʊ.di/ and the final /əm/ suffix, which often reduces to a schwa or a quick /əm/. The middle /d/ can blend with the preceding /oʊ/ if spoken quickly, and stress placement (second syllable) matters for intelligibility. Practice slow, then progressively speed up while maintaining distinct vowels and clear /di/ sequencing; refer to IPA guides to anchor mouth positions.
Does the pronunciation shift when used in compound terms like 'neodymium magnets' or 'neodymium-doped' due to linking? In compounds, you’ll typically retain the same syllable stresses (ne-OD-ee-um magnets). The liaison and rapid speech can make the middle vowels slightly elide in fast speech, but the primary stress remains on the second syllable. Ensure the /di/ remains a distinct segment even when a following word starts with a consonant.

Neodymium derives from the Greek neos/neos- meaning new, and odussomai meaning to obtain or to get, combined with -ium as a common chemical element suffix. The term was coined in the early 20th century as part of the systematic naming of rare-earth elements. The element was discovered in 1841 by Swedish chemist Carl Gustaf Mosander when he separated didymium into actual neodymium and praseodymium in later work. The name was chosen to reflect its relative novelty among the lanthanides, distinguishing it from previously known rare-earth metals. Over time, the word entered scientific literature and industrial catalogs, becoming standard in periodic tables and textbooks. Its usage broadened with magnet technology in the 1950s and 1960s, cementing neodymium’s role in modern electronics and metallurgy. The first known use in published English appears in chemical researchers’ reports from the late 19th to early 20th century, with widespread adoption by mid-century as the properties of neodymium magnets became pivotal in industry.
